CVE-2018-14942
Harmonic NSG 9000 devices allow remote authenticated users to conduct directory traversal attacks, as demonstrated by "POST /PY/EMULATION_GET_FILE" or "POST /PY/EMULATION_EXPORT" with FileName=../../../passwd in the POST data.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.01%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
